R&D Tax Credit for Agriculture: What George v. Commissioner Means for Row Crops and Livestock

For decades, the question of whether a farm could claim the federal R&D tax credit was answered with an uneasy "probably." Section 41 of the Internal Revenue Code never excluded agriculture, but the Internal Revenue Service routinely challenged farm claims as ordinary production activity rather than qualified research. On February 3, 2026, the United States Tax Court issued George v. Commissioner, T.C. Memo. 2026-10, and the uneasy "probably" became a clear "yes, when properly documented."

The case directly addressed poultry research, but the legal framework the court applied is industry-neutral. The same Four-Part Test, the same pilot model rule under Section 174, and the same documentation standards apply to row crop trials, seed selection studies, irrigation engineering, soil amendment testing, dairy nutrition trials, and aquaculture research. Industry coverage of George commonly notes that it builds on earlier agricultural recognition for row crop farming, generally cited as JG Boswell Co. v. Commissioner. Together, the two cases are read as confirming that agriculture, from row crops through animal production, qualifies under the same Section 41 framework that applies to software, manufacturing, and engineering. This guide walks through what the court actually held in George, how the framework extends to row crops, and what farmers and their CPAs need to do to claim the credit defensibly.

Case Snapshot: George v. Commissioner

The petitioners were Gary C. George, the sole shareholder of George's of Missouri, Inc. (GOMI), and his wife Robin A. George. GOMI is the live production arm of one of the largest fully integrated poultry operations in the United States, responsible for the chicken supply chain from incubation through transport for processing. GOMI claimed Section 41 research credits for seven research trials conducted between 2012 and 2014, including trials on vaccine priming methods, probiotic feed additives, drug dosage protocols, and a new genetic broiler line. The credits flowed through to the Georges, who applied them across tax years 2011, 2012, 2014, and 2016.

The Internal Revenue Service disallowed every claimed credit and sought accuracy-related penalties under Section 6662(a) for the 2014 and 2016 tax years. Judge Travis Greaves, writing for the Tax Court, allowed some trials and disallowed others. The case turned almost entirely on contemporaneous documentation. As the opinion put it, "Forget the proverbial chicken or the egg; today we are called to answer which came first, the research or the research credit study?"

Why This Ruling Covers Row Crops Too

Section 41(d)(1) defines qualified research without reference to any industry. The four statutory requirements apply uniformly to a software engineer running an A/B test, a manufacturer iterating on a tooling design, a poultry producer trialing a new vaccine schedule, and a row crop farmer evaluating a new corn hybrid against last season's variety. The court in George did not create a special agricultural rule. It applied the existing Section 41 framework to a farm and explained how each element is satisfied by systematic on-farm experimentation.

That analysis is portable. Industry commentary tracking George commonly pairs it with JG Boswell Co. v. Commissioner, which is cited for the proposition that row crop farming research can qualify. Read together, the two cases address the two halves of agricultural production. JG Boswell is read for the row crop side of the framework. George is the more technically detailed of the two, with explicit holdings on the pilot model rule under Section 174, the independence of supply and wage QREs, and the limits of base period estimates under the Cohan rule. A row crop producer who plants two adjacent fields with different hybrids, applies a controlled fertilizer protocol, captures yield data by plot, and documents the hypothesis being tested is doing the same kind of work the court evaluated. So is a producer testing a new irrigation method against a baseline, comparing soil amendments by replicate plot, evaluating a new pest management protocol, or trialing equipment modifications for specific field conditions. The science differs, the framework does not.

The Four-Part Test, Applied to a Farm

Section 41(d) requires that qualified research satisfy four requirements. Each one is met routinely on innovation-driven farms, although the language is unfamiliar to many producers.

Permitted Purpose

The research must be undertaken to develop or improve a product, process, technique, formula, or invention used in the taxpayer's trade or business. Improving a yield, growth rate, feed conversion ratio, disease resistance level, or processing technique each satisfies this requirement.

Technological in Nature

The research must rely on principles of the physical or biological sciences, engineering, or computer science. Agronomy, animal science, soil science, plant pathology, and engineering all qualify. Crop and livestock research routinely apply these disciplines.

Elimination of Uncertainty

At the outset of the activity, there must be uncertainty about whether the desired outcome can be achieved or about the appropriate method or design. The court in George emphasized that uncertainty is judged from the perspective of the taxpayer's specific operation, not from a published academic benchmark. A regional row crop trial under specific soil and weather conditions can present genuine technical uncertainty even when general principles of the underlying science are established.

Process of Experimentation

The taxpayer must evaluate one or more alternatives through a systematic approach. The court explicitly rejected the IRS argument that overlapping trials or extraneous variables disqualify the activity, observing that integrating real production conditions was often the entire point of the research. Trial protocols, control groups, replicated plots, and measured outcomes evidence the process of experimentation.

Three Rulings That Reshaped Farm R&D Claims

1. The Pilot Model Rule Under Section 174 Covers Experimental Crops and Animals

Treasury Regulation Section 1.174-2 treats the cost of constructing or developing a "pilot model" of a product as a research expenditure. The court in George applied the pilot model rule to the experimental flock of broiler chickens, holding that the birds existed to evaluate and resolve technical uncertainty about a vaccine and antibiotic protocol. The cost of feed for those experimental birds was therefore deductible under Section 174 and eligible to be a qualified research expense for Section 41 purposes.

This logic is portable to row crop research. An experimental crop plot grown to test a hypothesis is a pilot model in the same sense the experimental broilers were. The seed, treated inputs, and other supplies consumed in growing the experimental crop can qualify under Section 174, subject to the same documentation rigor.

2. Supply Expenses Can Be Claimed Without Claiming Wages

The taxpayer in George chose not to claim wage QREs because the calculation effort was not justified by the additional credit value. The IRS argued that supplies should be disallowed when wages were not also claimed. The court rejected that argument. Supply QREs and wage QREs are independent under Section 41(b), and a taxpayer can claim one without claiming the other.

For farms with seasonal labor, contract workers, or split entity payroll structures, this matters. Tracking research-specific wages on a farm operation can be impractical even when the underlying research is robust. The court confirmed that the practical decision to skip wages does not impair the supply claim.

3.Base Period Estimates Require a Factual Foundation

The credit calculation under Section 41 requires QRE data for the base period as well as the credit year. The taxpayer in George attempted to estimate base period QREs without a sufficient factual foundation, relying on the Cohan rule (Cohan v. Commissioner, 39 F.2d 540 (2d Cir. 1930)). The court rejected pure estimates and treated this as a meaningful limit. With base period data inadequate, the taxpayer was placed on the alternative simplified credit method at the lower 6% rate.

The takeaway is direct. If a farm wants the higher regular credit rate, the base period needs real data. If only the credit year is well-documented, the credit can still be claimed under the alternative simplified credit, but at the lower rate.

Documentation: What Won, What Lost

The most useful part of the opinion for farmers is the trial-by-trial analysis. The court walked through each of the seven research trials and explained why some qualified and others did not. The pattern is consistent and instructive.

The pattern is the same for every trial: where the records created in the normal course of running the trial established hypothesis, design, and outcome, the activity qualified. Where the records were thin, contradicted the claim, or were assembled retrospectively, it did not.

For row crop and livestock operations, the documents that should already exist in the normal course of business are often the strongest evidence. Seed treatment logs, planting maps, agronomic plans, soil and tissue test results, scout reports, yield monitor data, ration formulations, herd health records, and lab test results are all contemporaneous research records when the trial is set up correctly. A research credit claim does not need to invent a separate paper trail; it needs the existing paper trail to clearly answer four questions: What was the hypothesis? What was the trial design? What was actually done? What was measured?

Section 174A and the OBBBA Window

The One Big Beautiful Bill Act, signed into law on July 4, 2025, created Section 174A of the Internal Revenue Code, restoring immediate expensing for domestic research expenditures. For tax years beginning after December 31, 2024, qualifying domestic research expenses are once again deductible in the year incurred rather than capitalized and amortized over five years under prior Section 174. The IRS published procedural guidance in Revenue Procedure 2025-28.

The OBBBA framework gives different paths to small and large taxpayers, and both matter for agriculture.

Path 1: Retroactive Election for Small Businesses

Eligible small businesses (generally those that meet the Section 448(c) gross receipts test, meaning average annual gross receipts of $31 million or less, computed at the controlled group level for the first taxable year beginning after December 31, 2024) can elect to apply Section 174A retroactively to tax years 2022, 2023, and 2024. The retroactive election is made on amended returns or Administrative Adjustment Requests under procedures published in Revenue Procedure 2025-28. The outside deadline is the earlier of July 6, 2026 or the applicable statute of limitations for each taxable year. Many farms operating as S corporations, partnerships, or LLCs taxed as flow-through entities qualify under the small business definition.

Path 2: Acceleration for Larger Taxpayers

Taxpayers above the $31 million gross receipts threshold cannot make the retroactive election. They have a different transition path. They can accelerate the recovery of their unamortized 2022-2024 capitalized domestic R&E balance by deducting the remaining amount fully in 2025 or ratably over 2025 and 2026, via an automatic method change concurrent with the change to Section 174A. This path matters for larger row crop operations, integrated livestock producers, and food science businesses that exceed the small business threshold but still have significant unamortized R&E from the post-TCJA capitalization years. It is not a refund mechanism. It is an acceleration of deductions that would otherwise be recovered over the original five-year amortization period.

Section 280C(c) Coordination: Do Not Skip This

The OBBBA reinstated the pre-TCJA structure of Section 280C(c). Any taxpayer claiming the Section 41 research credit must either reduce the Section 174A deduction by the amount of the gross credit, or elect under Section 280C(c)(2) to claim a reduced credit and keep the full deduction. The election is made on Form 6765, Item A, and the choice materially changes the after-tax economics of the credit.

For small businesses making the Section 174A retroactive election, retroactive application of Section 174A also requires retroactive application of the conforming Section 280C(c) treatment for each year. Eligible small businesses can also make or revoke a late Section 280C(c)(2) election on amended returns filed during the one-year period after enactment, on the same July 6, 2026 outside deadline. Once the late election is made for a given year, it is irrevocable for that year.

The practical takeaway for farms is that the Section 41 credit cannot be modeled in isolation. The credit value, the Section 174A deduction, and the Section 280C(c) election interact, and the best election varies by entity type, marginal rate, state conformity, and whether the taxpayer expects taxable income in the years at issue. Run the math both ways before filing.

Rev. Rul. 82-49: Recovering R&D Credits from Closed Years

The standard deadline for claiming a refund under Section 6511(a) is generally three years from the date the original return was filed or two years from the date the tax was paid, whichever is later. Beyond that window, a refund claim is barred. Many farms have years of qualifying research that fall outside the three-year window, and on first reading the rule appears to permanently close the door on those years.

It does not. Revenue Ruling 82-49, 1982-1 C.B. 5, addresses this exact situation. The ruling held that the failure to claim the investment tax credit on Section 38 property in a closed year does not prevent the taxpayer from carrying forward any unused credit from the closed year into an open tax year. Section 6511 bars a refund for the closed year itself, but it does not bar the recomputation of a carryforward into an open year. The Section 41 R&D credit is part of the Section 38 general business credit and is subject to the same Section 39 carryforward rules. The IRS confirmed in Letter Ruling 201548006 that the same analysis applies to Section 38 general business credits, including for flow-through entities such as S corporations and partnerships, which are common entity structures in agriculture.

The practical effect for farmers is substantial. A row crop operation that conducted qualifying research in 2018 but never claimed the credit can, in many cases, recompute the closed-year credit and use the carryforward in a current open year. The closed-year refund is unavailable, but the carryforward path remains open. Strike has a separate, dedicated guide on this topic. Read Claim Unused Business Tax Credits with Rev. Rule 82-49 for the full mechanics, including when and how to recompute the prior-year credit and document the carryforward.

Form 6765 Section G in 2026

The Internal Revenue Service released the revised Form 6765 with a new Section G (Business Component Information). Per the current IRS Form 6765 instructions and the IRS announcement of October 1, 2025, Section G is optional for tax years beginning before 2026 (so optional for the 2024 and 2025 tax years). Section G is mandatory for tax years beginning after December 31, 2025, which means most filers must complete it on 2026 returns filed in 2027.

Section G requires project-level reporting of qualified research activities, including a description of the business component, the type of business component (product, process, software, formula, invention, technique), the information sought to be discovered, and the qualified research expenses associated with that component.

Two Exceptions Most Agriculture Filers Should Know

Section G is not required for two categories of filers, both of which apply commonly in agriculture:

1. Qualified Small Business taxpayers as defined under IRC Section 41(h)(3) electing the reduced payroll tax credit. This applies to early-stage agribusinesses and ag-tech companies that meet the gross receipts and age tests for the QSB payroll credit election.
2. Small-credit filers with total qualified research expenses of $1.5 million or less (determined at the controlled group level) and gross receipts of $50 million or less (under Section 448(c)(3) without regard to subparagraph (A)), claiming the research credit on an originally filed return. Many independent row crop and livestock operations land inside this carve-out.

Filers outside these exceptions must complete Section G in full. For a farm, this means the trial-level documentation that already supports a defensible Section 41 claim under George v. Commissioner is now also the documentation needed to complete Section G. A farm that documents each trial as its own business component, with a clearly stated hypothesis, design, and measured outcome, will find Section G straightforward. A farm that aggregates research at the entity level, with no trial-by-trial substantiation, will struggle.

The takeaway is that the documentation framework for the credit and the documentation framework for Form 6765 Section G are now functionally identical. The work required to defend the credit is the work required to file the form.

Action Checklist for 2026

For row crop and livestock producers and the CPAs who serve them, six items deserve immediate attention:

1. Inventory current and recent research activity at the trial level. List each trial conducted in 2022 through 2025 with the hypothesis, design, and outcomes. Identify which trials have contemporaneous documentation and which do not.
2. Evaluate the Section 174A retroactive election for any of those years where the operation qualifies as a small business. The outside deadline is July 6, 2026 or the applicable statute of limitations, whichever comes first.
3. For larger operations, evaluate the acceleration method change for unamortized 2022-2024 R&E balances on the 2025 return. Decide between full recovery in 2025 and ratable recovery over 2025 and 2026.
4. Coordinate Section 280C(c) with every Section 174A election or method change. Run the credit math both ways (gross credit with reduced deduction versus reduced credit with full deduction) before filing.
5. Apply Rev. Rul. 82-49 to closed years with unclaimed qualifying research that would generate a credit carryforward into the current open year. Recompute the closed-year credit, document the carryforward, and apply the carryforward against current-year liability.
6. Build documentation systems for the 2026 tax year at the trial level so that Form 6765 Section G can be completed cleanly and the underlying credit is defensible under the framework the Tax Court applied in George v. Commissioner.
